Errors linking the project - ppaslin.sh - Segment fault / Bus error: 10

[Pepin]

Hello everyone.

First at all, congratulations for this forum!

My English is very bad, excuse me if my writing is not as good as I would like.

I installed Lazarus following instructions and the installation ended successfully but, when I trie to compile a project I get errors in the linking phase:

    Ppaslink.sh: line 9: 62623 Bus error: 10
    An error occurred while linking
Or:
     Ppaslink.sh: line 9: 64135 Segmentation fault: 11
     An error occurred while linking


I'm using a MacBook with M3 chip and macOS 15.4 operating system (Sequoia)

Does anyone know what it can be due to and how it can be solved?

Thank you very much.

Looks like a hardware problem: a bus error can not be caused by a fpc/lazarus compile. A bus error is always a hardware issue.

I too just started getting this after upgrading to Sequoia (Lazarus 4.0RC1 (rev Unknown) FPC 3.2.2 aarch64-darwin-cocoa, was compiling & linking fine before upgrading to Sequoia)

I also get this problem doing a new install on sequoia using the fixes_4 branch:

Did you exclude this solution ?

actually, to my surprise, it did. I had -WM11.0. Changing it to -WM10.9 resulted in linker errors about missing stuff, but it linked with -WM10.15

Thanks!

Wrong. A bus error occurs when some memory is accessed in an unaligned way while it should be accessed in an aligned way. And even though Aarch64 allows for the operating system to enable unaligned accesses to normal memory there is still memory (e.g. device memory) that has alignment requirements.
